- W2089849463 abstract "The high-frequency dynamics of the molecular glass-former propylene carbonate has been investigated by the use of inelastic x-ray scattering (IXS) spectroscopy. The inelastic contribution to the spectra was analysed with a damped harmonic oscillator model. Up to a momentum transfer of Qc 5 nm−1 and an energy of Ωc 8 meV, acoustic-like excitations with a Q2-dependence of the linewidth and a linear dispersion, consistent with the low-frequency sound velocity as measured by means of Brillouin light scattering, were found. At Qc, a clear change in the excitation behaviour is found, which is characterized by a bending of the dispersion and a deviation from the Q2-behaviour of the linewidth. A comparison with reported IXS data for other glass-formers reveals a common tendency to bend upon approaching a pseudo-Brillouin zone boundary defined at QFSDP /2. The comparison also shows that the energy of the acoustic excitations, relative to that of the boson peak (Ω/EBP), extends to larger values for glasses without a strong directional bonding topology." @default.
